Ok ..so we put the free corals * that came from bar members, into the 50 gal.. They are flourishing.. Green stars are growing everywhere...><. We put a sea hare in there too.. Omg its quite funny. And Roger Rabbit (my son's name for it) is doing its job of eating the algae. I see new snails all the time. In the 135 gallon, 2 hermit crabs appeared out of no where. So the hitchhikers in there now include a sea cucumber and a few hermit crabs. Little starfish are growing all over the sides. We have reached a 4 count.. wonder where they are coming from..
